PLUSPOEUSB C to Slim Tip Adapter, Convert Lenovo Square Charger to Type C, for Lenovo Thinkpad, Samsung S8/S9/Note, Nintendo Switch, and Any USB C Devices, Max 65watt

This is an adaptor for a Lenova laptop that is the same wattage as my new computer. I have several DART FINsix adapters. These are brilliant adapters, but the company went out of business very rapidly. I used this adapter to work with the Lenovo tip to convert it to a type C to work with my new Dell. Works great!The only thing that matters is the C-side, otherwise any of the tips that you can obtain to convert power will do. So if you have an adapter without a type-C tip, look for an adapter tip of your current adapter. The thing that does matter is that both the tip and the adapters are 65 watts.Many, many fabulous designs such as the FINsix DART come and go very quickly. I was dreading having to go with the huge brick that I knew Dell was going to send (which they did), so these Lenovo to C adapters are priceless. I'm going to buy a few more, to work with my other adapters. When I find something that works, I definitely believe in redunduncy, as these may disappear quickly, too.

Plugged PLUSPOE USB C to Slim Tip Adapter into several Authentic Lenovo slim tip (square) AC power adapters 45w, 65w and 90w into several Lenovo laptop models from T470 through T14 G3.Upon booting various laptops halted with this message: (see screenshot)"The connected AC adapter has a lower wattage than the recommended AC adapter which was shipped with the system. To use AC power please connect the AC adapter which was shipped with the system."Pressing [ESC] on the boot up message allowed the laptop to load Windows. While using Windows constant "Lenovo Hardware Settings" pop ups appeared stating: (see screenshot)"Incorrect AC adapter is attached. This AC adapter cannot provide enough energy power for normal operation of your computer. You may be able to charge your battery with this AC adapter if your computer is in sleep or shut-down states. [ ]Do not show this message again"This adapter used with an authentic 135w Lenovo power adapter did successfully charge my Lenovo laptop while it was shut off which for my case is what I needed so I did not return the product.Buyer be warned!

My laptop came with a 65w charger. This adapter is supposed to be 65w but my laptop says slow charger connected. The charger I connected the adapter to is a genuine lenovo 90w charger. So it does work but is underpowered for my case

Works well for the money. Not much else to add

I purchased this product to adapt from a 100w Lenovo charger to a Lenovo laptop. It fits, however it reduces the chargers ability to fast charge, greatly reducing the charging time.

Life saver. Bought a laptop power bank which has no dc jack and did not come with usb-c adapter. This allowed me to charge a usb-c charger laptop. Also works for MacBook Pro

Before purchase I read the many reviews mentioning that laptops were complaining this charger was underpowered. My new laptop shipped with only a 65W power supply, which is the rating on this adapter, so I figured I'd roll the dice. It does work to charge the computer, but I still get the "slow charger" warning.Two stars because it is not capable of the 65W it claims to be, though it still does charge. Worth it so I don't have to toss my old second charger, I guess.

seems to do the job of converting from the old Lenovo-plug.
